Badass Digest brings word that Marvel favorites Christopher Markus and Stephen McFeely are set to pen the scripts for the two-part Avengers: Infinity War, which Anthony and Joe Russo were recently confirmed to direct. The pair have previously written Captain America: The First Avenger, Captain America: The Winter Soldier, and the upcoming Captain America: Civil War. They also did re-write work on Thor: The Dark World and created “Marvel’s Agent Carter.”

“It’s Thanos against everyone,” star Josh Brolin told us about the “Phase Three” capper late last year, which is believed to involve the Mad Titan’s quest to bring together the six Infinity Stones we’ve seen appear throughout the history of the Marvel Cinematic Universe.

Guardians of the Galaxy director James Gunn also chimed in previously on the idea of the Guardians meeting the Avengers saying: “When I’m asked about the Guardians and their future, and whether they’ll meet up with the Avengers I really don’t have all that much to say, because some of it isn’t decided yet, and I don’t want to give away what is decided.”

Production on Captain America: Civil War is set to begin soon in Atlanta, Georgia with the film targeting a May 6, 2016 release. The third film in the Captain America franchise will bring the classic storyline from the comics to life pitting Cap (Chris Evans) against Iron Man (Robert Downey Jr.), as well as introducing Black Panther to the Marvel Cinematic Universe with actor Chadwick Boseman ahead of his own film later in Phase 3.
